Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to roofs of buildings, and in particular to triangular roofs with multi-layered spaces.

[Conventional technology]

In particular, as a renovated roof, for example, the triangular roof with living or storage space is created by removing the old roof of an existing building with a frame structure and using the exposed existing girders as a base, and creating a triangular roof with a living or storage space in place of the old roof. invented,
This has already been proposed in Japanese Patent Application No. 159107/1983 (Japanese Patent Application No. 14943/1983).

[Problem to be solved by the invention]

According to this proposal, since it is based on the existing girder of an existing building, this triangular roof is generally particularly suitable for building a single-story frame, and is suitable for building multi-story spaces such as two or three stories. Sometimes it is necessary to install an additional floor mid-height of the roof.
In the case of on-site construction, for example, even if you try to increase the factory processing rate and promote panelization, the spacing of the existing girders that serve as the base will differ depending on the size of the existing building, so the floor surface and As long as the
This would require a large number of panels with different dimensions.

On the other hand, if this renovated roof is installed on an existing building with a relatively large gable width, or if the flat side of the existing building is used as the gable side of the renovated roof, the base of the triangular roof will expand and the roof height will increase. It is often considered appropriate to have a structure that is naturally high and has an overlapping space.

The present invention has been made from this viewpoint,
The purpose is to provide a triangular roof that is suitable for panelization, is simple, and has a multilayer space with excellent strength.

[Means to solve the problem]

The present invention comprises a lower triangular roof frame having the same shape and dimensions, an upper triangular roof frame, an interposed gable panel having the same shape and dimensions as the gable panel of the upper frame and having been inverted vertically, and a roof base on the flat side of the frame. In other words, the present invention provides a floor structure which is arranged adjacent to each other in the front and back on the flat side, isosceles triangular end panels which are installed opposite to each other on both ends of the end sides of the floor structure, and between the apexes of these end panels. A plurality of lower triangular roof frameworks each having an erected purlin, a floor structure and a gable timber installed between the purlins; and a gable panel interposed in an upside-down manner between adjacent gable panels of these frameworks on the gable side; An intervening gable panel of the same shape and size; an upper triangular roof frame of the same shape and size as the above-mentioned frame, which is placed on the bottom of the intervening gable panel positioned above; a flat side surface of each triangular roof frame; The present invention relates to a triangular roof having a multi-layered space characterized by being provided with a roof base and a roof base provided thereon.

[Effect]

In the present invention, each triangular roof frame can be configured in advance and stacked one after another on an existing or newly constructed building structure, or the lower triangular roof frames can be configured on site so that the resulting structure is stacked. Use as a.

At this time, each triangular roof frame has a triangular shape on the gable side, and is equipped with a floor structure, tall timbers, and purlins.
Furthermore, since the intervening gable panel is interposed between the lower triangular roof frames, the roof load is effectively distributed and supported by each frame.

〔Example〕

The following description will be made according to the drawings showing the embodiments: 1
is a triangular roof having a multilayer space according to the present invention, and in this example, the old roof of an existing building 7 with a frame structure was removed, and a new roof was constructed using the exposed existing girders as a base and using architraves 8 as a base. It is said to have been used as a renovated roof.

The triangular roof 1 includes a plurality of lower triangular roof frames 2a, a single upper triangular roof 2b, and an intervening structure, which are arranged adjacently in the front and back on the flat side (the gable side when the existing building 7 is used as a reference). It is equipped with a end panel 4'.

These upper and lower triangular roof frames 2a and 2b
These are designed to use unit frames with predetermined dimensions, so that they all have the same shape and dimensions, and are designed to have a similar shape to the triangular roof 1 on the gable side.

Each triangular roof frame 2a, 2b includes a floor structure 3, a gable panel 4, a ridgepole 5, and a gable wood 6'.

That is, each of the floor structures 3 uses 2 x 6 inch structural materials, and a large number of joists 30 are arranged parallel to each other at predetermined intervals between a pair of gable joists 31, and flat sides perpendicular to each other are arranged at the front and rear ends. Front and rear nose joints 3
2 are arranged and fixed with nails to form a framework, and furthermore, a floor board 33 made of structural plywood is nailed to the upper surface. And this floor structure 3
On the above-mentioned pair of joists 31, there is a gable panel 4 of structural plywood in the form of a right-angled isosceles triangle selected from isosceles triangles including equilateral triangles so as to define the roof slope.
The gable panels 4 are installed opposite to each other at both ends of the gable side of the floor structure 3 by placing them upright and directly nailing and fixing them via L-shaped fixing fittings (not shown). Between the orthogonal apexes of these end panels 4, single purlins 5 made of 2 x 6 inch structural members are fitted and fixed in a manner that matches the length of the flat side. Between the nose joint 32 and the ridgepole 5, a gable barrel tree 61 is installed along with the gable panel 4, respectively.

Among the unit frames constructed in this way, the lower triangular roof frames 2a are arranged adjacent to each other on the architrave 8 as described above, and at this time, the lower triangular roof frames 2a are adjacent to each other on the gable side. An intervening gable panel 4' is placed between the gable panels 4 and the frame 2.
They are each interposed and fixed so as to close the space between a.

The interposed gable panel 4' is of the same shape and size as the gable panel 4, and the interposed gable panel 4' is turned upside down to form a space between the lower triangular roof frames 2a. It is done in a mating manner.

On the other hand, the upper triangular roof frame 2a is disposed on the upper base of these intervening gable panels 4', thereby forming a multilayer frame 6.

At this time, the nose joints 32 located at both ends of the gable side of the upper triangular roof 2b are located on each purlin 5 of the lower triangular roof 2a, so that the load can be distributed and supported by each lower triangular roof frame 2a. It is set as.

Upper and lower triangular roof framework 2 installed in this way
On the flat side surfaces of a and 2b, that is, the surface that demarcates the inside and outside of the triangular roof 1, a large number of barrel trees 60 and fall prevention devices 62 are interposed between each ridgepole 5 and the joist 30. A roof base 63 is provided on the surface of which a large number of structural plywood sheets are stretched.

Reference numeral 64 in the figure is a gable provided in this example by extending the nose joint 32 so as to protrude toward the gable side.

This example has been described above, but in carrying out the present invention, the floor structure is made of a non-wood veneer, such as a concrete floor panel installed between opposing girders, and the end panel is made of particles. It is also possible to use an ALC panel, which itself has excellent strength, and is reinforced with a board or built-in reinforcing bars. Also,
This wife panel is Japanese Patent Application No. 61-285095 (Japanese Patent Application No. 63-
138050), it is possible to further standardize parts.

Furthermore, when connecting triangular roof frames, the number of parts can be reduced by sharing the nose joint of the floor structure between adjacent lower triangular roof frames, and similarly connect the ridgepole of the lower triangular roof frame with the upper triangular roof frame. It is also possible to share the nose joint of the floor structure of the triangular roof frame. Note that the ridgepole and nose joint shown protruding from the gable panel are for attaching the gable.
Of course, it may be removed if unnecessary.

By the way, although this example is provided with a two-layer living or storage space, it is also possible to obtain a three-layer multilayer space by configuring, for example, six triangular roof frames. Although not shown in the drawings, it is of course necessary to provide an opening in the floor to connect each layer with a staircase, storage staircase, or ladder.

On the other hand, the roof can be finished in various ways, such as slate, steel plate, etc., in addition to the roof tiles of this embodiment. Although the interior is not particularly shown, this can also be selected as appropriate. It is of course optional to lay vinyl floor tiles or tatami mats on the floorboards. Other examples of roof sheathing boards include, for example, Japanese Patent Application No. 61-259643 filed by the present applicant (Japanese Unexamined Patent Publication No. 63
-114747) can be used. Moreover, although wooden structural materials were used for the joists, nose joints, purlins, barrels, and fall prevention materials in this example, other structural materials such as lightweight steel sections may be used depending on the strength and other design conditions.

As is clear from the above, when carrying out the present invention, various changes may be made to the specific materials, shapes, structures, dimensions, installation procedures, etc., as long as they do not go against the gist of the invention. It is not limited to the example described.

[Effects of the Invention] As described above, the present invention includes a floor structure that is arranged adjacent to each other in the front and back on the flat side, isosceles triangular end panels that are installed opposite to each other at both end ends of the floor structure, and a space between the apexes of these end panels. a plurality of lower triangular roof frameworks each having a purlin installed on the roof structure and a floor structure and gable timbers installed between the purlins; and a gable panel interposed in an upside-down manner between adjacent gable panels of these frameworks on the gable side; An intervening gable panel of the same shape and size; an upper triangular roof frame of the same shape and size as the above-mentioned frame, which is placed on the bottom of the intervening gable panel positioned above; a flat side surface of each triangular roof frame; Since the triangular roof structure is characterized by having a roof base provided on the roof, it is possible to standardize the members by standardizing the triangular roof frame, the gable panels used for this, and the intervening gable panels, and the processing required for these. Efficiency can be improved and inventory of parts can be reduced.

A triangular roof can be constructed by installing the required number of triangular roof frames in a stacked manner according to the floor level, thereby ensuring that each space is of the same height as required. In addition, since the ridgepole of the lower triangular roof frame is placed so as to overlap the floor structure position of the upper triangular roof frame, this may occur horizontally in the upper and lower middle positions of the lower space and become an obstacle to space utilization. Nor.

In addition, each roof frame and intervening gable panel is shaped like an isosceles triangle on the gable side, making it possible to obtain a structure for each floor that itself has excellent strength, and the load is evenly received and distributed downward. Therefore, the triangular roof as a whole can be made extremely strong.
